I'm not sure who exactly Bill Hamer is in the 'Ghost Story'. It could be a character specific to that particular 'Ghost Story' and more context from the story itself would be needed to give a more detailed account.
Well, in a 'Ghost Story', Bill Hamer could be any number of things. He could be a local in a haunted town where the story is set. He might be the person who discovers the secrets behind the hauntings. For example, if the ghost story is about an old mansion, Bill Hamer could be the caretaker who starts noticing strange things. He could also be a journalist trying to uncover the truth about the ghostly happenings for a story. Or he could be a relative of someone who has a connection to the place that is haunted. However, without more information from the actual 'Ghost Story', we can only speculate.
